Frequently Asked Questions

What type of weather does Perry Weather monitor?
Perry Weather’s software and weather stations monitor real-time lightning strikes, live and forecasted heat stress measurements, live and future radar, wind speed, temperature, humidity, air quality index (AQI), wind chill, rainfall totals and more.
Our system also tracks and stores easily-downloadable historical weather data for your location.
Does Perry Weather support multi-jurisdictional or regional deployments?
Yes! Our platform can manage weather data and alerts across multiple jurisdictions or regions from a single, centralized dashboard, optimizing coordination and response times.
Why is Perry Weather better than free weather apps on my phone?
Free weather apps are great for everyday personal use, but extremely limited for use in schools, organizations, and businesses. You can’t build weather safety policies that notify your organization about what actions need to be taken in a weather safety situation. The data can be up to an hour old and coming from the nearest airport miles away, often painting a dramatically different picture than the true conditions on the field or at your location.

How do you detect lightning?
Perry Weather detects all lightning strikes within your area down to 100 meters of accuracy, using the National Lightning Detection Network, the same system used by the U.S. government and military.
No more scrambling to figure out what to do when lightning strikes. Our system gives you an accurate weather forecast, sends alerts based on your policies, and triggers an outdoor warning system to alert everyone else, ensuring a coordinated, swift response to keep everyone safe.
How many of my staff members can access the software?
Our team will set you up with as many users as you need so you can assure your whole staff is on the same page when it comes to daily weather monitoring and alerting. Talk with our team today about our options for both full-access and notification-only users.
Can the public access your software?
Full access to Perry Weather’s software is intended to keep your staff on the same page. However our system can seamlessly integrate with school websites and scoreboards so you can put our forecast and real-time weather insights dashboard, including radar and lightning strike timers, for the public to access at all times.
Do we need to give you access to our Wi-Fi?
Perry Weather units are completely wireless and use cellular networks to provide strong connection at all times. Have poor cellular service in your area? Our built-in cellular VPN will always connect to the carrier with the best current signal ensuring a positive connection.
How do we set up all of our users and our weather alert policies?
We take this out of your hands completely. Your dedicated account manager will get you all set up with your specific weather policies and get all of your users set up on the software so you can be ready to go upon install.
Can Perry Weather integrate with our existing notification systems?
Yes! We offer seamless integration with various notification platforms and emergency response systems and make integrating your policies simpler than ever.
